Thanks for this post and the one on CSI, John.
I've seen the $10M/life saved figure elsewhere recently.
It's my understanding that another figure used in the nuclear industry is
$10k per REM avoided. Is that number up-to-date?
My understanding is also that an estimate of latent cancer fatalities from
large doses of radiation is 0.0005 LCF/person-REM -
http://twilight.saic.com/newtec/comm/EIS_Sample.pdf .
It's complicated, since latency is not as bad as immediate death, but if you
do the math, you come up with $20M dollars spent per LCF avoided.
I know, some people will be offended about placing _any_ value on human
life, but I encourage them to read what John posted (included below). Also
consider that if you were on your death bed, how much would you expect
society to pay to keep you alive. I must have low self-esteem, because I
wouldn't want them to waste $10M perpetuating my lame humor. That money
would be better spent elsewhere, like by sending my kids to Nuke College -

No offense intended to anyone, particularly those at downwinders who I have
cc'd - many of whom who have been injured by atmospheric weapons tests or
occupational exposures to various things.
Regards,
Jim

Is Your Life Worth $10 Million?
Nope. But your grandson's will be.
By Steven E. Landsburg
Posted Monday, March 3, 2003, at 6:22 AM PT
While touring the magnificent old Dupont estate, I overheard an awestruck
gardener mutter, "You can see why these people would have hated to die worse
than anybody." I know what he meant. Life is dear, but life is dearer when
you're rich.
You're richer than your grandparents, so your life is worth more than
theirs. That's why you live in a safer world than they did: As life gets
more valuable, we strive harder to protect it.
What does it mean to say that one life is "worth more" than another? Aren't
all lives infinitely precious? Well, no, at least not in any sense that's at
all useful for making hard policy decisions about things like job safety and
access to medical care.
Economists measure the value of a life by people's willingness to pay for
safety. Suppose you'd willingly cough up $50,000—but no more—to shave one
percentage point off your chance of being killed in an accident. Then
(except for some technical adjustments I won't go into) we infer that the
value of your life is 100 times $50,000, or $5 million.
That's a useful measure because it bears directly on policy decisions. Take
the decision of how much to spend on fire safety. Should a town of 100
people spend $6 million on a piece of equipment that is likely, over the
long run, to save one life? Not if a life is worth only $5 million. Buying
the equipment means forcing the average taxpayer to spend $60,000 for a
level of safety that's worth only $50,000 to her.
Economists summarize that reasoning by saying, "It makes no sense to spend
$6 million to save a life that's worth only $5 million." What we really mean
by that is: "Let's not force people to buy more safety than they want to."
So, how do we find out how much a life is really worth? One of the best ways
is to measure how much extra you have to pay someone to take a dangerous
job. If lion tamers and elephant tamers have comparable skills and
comparable working conditions, but lion tamers earn $20,000 a year more than
elephant tamers, it's probably because that's what it takes to compensate
someone for the risk of being eaten by a lion. And if that risk amounts to,
say, an extra half-percent probability of dying on the job, then you figure
that the value of a life must be $20,000 per half-percent, or $40,000 per
percentage point, or $4 million.
So, once you carry out that experiment, how much does a typical life turn
out to be worth? Professors Dora Costa of MIT and Matthew Kahn of Tufts
point out that it depends on exactly when you asked the question. As incomes
have risen, so has the value of life. The increase is more than
proportional: A 10 percent rise in income is generally associated with about
a 15 percent rise in the value of a life. Between 1940 and 1980, according
to Costa and Kahn, the value of a life increased from about $1 million 1990
dollars to between $4 million and $5 million 1990 dollars.
(Other researchers, notably Harvard's Kip Viscusi, have found higher
numbers. Viscusi estimates that the value of a life in 1970 might already
have been as high as $8 million 1990 dollars.)
The upward trend is hardly surprising. For one thing, the mere fact that
we're richer now means that we can afford to pay more for just about
everything, including our own safety (and by implication our own lives). But
beyond that, there are a lot of reasons to value life more now than in the
past. There's a lot more to live for in a world with central
air-conditioning, high-speed Internet access, and advanced medical care.
Besides, life expectancies have increased by about 10 years since 1940.
Today's 50-year-old, with perhaps 30 good years ahead of him, will value the
remainder of his life more than yesterday's 50-year-old, who already heard
time's winged chariot drawing near.
Here's what's most important about these observations: Just as your life is
more valuable than your grandfather's, so your grandchildren's lives will
probably be more valuable than your own. So, when we make decisions about,
say, how much to spend on medical research, we should account for the fact
that future lives will be worth more than present ones. Even if it's not
worth spending $7 million to save your own paltry life, it might be worth
spending it to save your grandson's.
